Chaos as coordinated attacks hit Thailand

Four people have been killed and more than 30 injured in a series of coordinated bomb attacks that ripped through several Thai provinces within 24 hours, leaving tourists holed up in hotels and chaos on the streets.

Australian Justice Minister Michael Keenan, who was in Thailand earlier this year to discuss ways to combat extremism, said there had been no claims of responsibility as yet and it would be "premature to speculate on the identity of the perpetrators".

"Thai authorities believe them to be part of a coordinated attack," he told AAP in a statement.

Royal Thai Police deputy spokesman Pol Maj Gen Piyaphan Pingmuang said the blasts were not linked to international militants but instead "acts of sabotage", stemming from internal conflicts.

A number of suspects have been detained for questioning, the Bangkok Post reported on Friday afternoon.

The attacks come less than a week after voters approved a new, junta-backed constitution and during the midst of Queen Sirikit's birthday celebrations.

Edwin Weik, who has lived in Thailand for 27 years, said the perpetrators of the attack at Hua Hin on Thursday night must have known that tourists would be there before the queen's birthday on Friday when bars and pubs are not allowed to serve alcohol.
